GENERAL INFORMATION
 The KERN Pyramid Nano has been developed for applications which require maximum accuracy and surface finish on larger workpieces. An integrated automatic workpiece changer allows unmanned operations even for 5 axes simultaneous jobs.
Virtually Perfect Nano Precision
The precision of the Kern Pyramid Nano goes beyond nano precision with positional accuracy within ± 0.3µm. To demonstrate the accuracy of the Kern Machining systems with Hydrostatic drives, Kern was able to drill five consecutive holes into an actual hair from a Kern Employee. Not only is the Kern Pyramid Nano able to successfully position over the hair, it is able to make a clean hole through the hair because of how vibration free it is.
PRODUCT APPLICATION
The KERN Pyramid Nano is a cost effective nano precision maching and large volume cutting amchine. With precision features such as a laser tool length measuring system, touch probe system with infared transmission and hydrostatic axes and guideways the Kern Pyramid Nano is able to tackle precision machining operations other machines simply can't handle.
The KERN Pyramid Nano is perfect for making rapid prototypes, die and tool making as well as precision molds. The nano µm precision is perfect for making difficult to make parts.
TECHNICAL INFORMATION
 Hydrostatic drives and guideways
The hyrdostatic drives and guideways of the Kern Pyramid Nano allow for the most accurate surface finishing. The hydrostatic drives are also able to provide fast acceleration with maximum vibration dampening.
Advantages of the hydrostatic system:
- Finest surface finishes with hydrostatic dampening
- Smallest movements of the axes 0.1µm
- Wear-free guideways and drives
- Almost frictionless movements . no "slip stick" effect, even when moving in small increments
- Low sensitivity at high machining forces
- High dynamic rigidity
- Permanently cooled circulating hydraulic oil flows through axes, drives and machine frame
- The highly dynamic third axis construction does not require counter-balance weights
- All motors are mounted outside of the axes - thus minimizing possible temperature influence
- Approx. 50% lower energy costs in comparison to linear drives
- No unacceptable cogging effects, as seen with linear drives
